The development of human civilization clearly demonstrates that we’re a migratory species, with some of the most powerful nations on earth having been built around empires, adventurers and immigrants. Indeed, the most powerful man in America today, U.S. president Barack Obama, is proud to claim roots in countries as far flung as Ireland and Kenya. Today, there are about 232 million international immigrants in the world, and that number is increasing every year. Insidermonkey experts made a list of 10 countries where most immigrants come from today.

Not all of these nations, however, have governmental policies which facilitate or support immigration. According to a United Nations’ world migration report from October 2013, four of the countries on this list actively aim to decrease levels of immigration. Policies vary depending on the status of the migrants, however, with most countries aiming to bring in more highly-skilled workers. Some countries favor certain nationalities over others, or target specific groups for deportation. You can also check our list of the 10 Most Successful Immigrants in America and Their Companies.
